ZyXEL P-662H-D1 routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.

The basic process to open a port is:

  1. Setup a static IP address on either your computer or device that you want to forward a port to.
  2. Login to your ZyXEL P 662H D1 router.
  3. Navigate to the port forwarding section.
    • Click the Network link.
    • Click on NAT.
    • Click the Port Forwarding button.
    • Select User define in the drop down.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your ZyXEL P-662H-D1 router.

We think that forwarding a port should be easy. That's why we created Network Utilities. Our software does everything that you need to forward a port.

Step 1

It is important to setup a static ip address in the device that you are forwarding a port to. This ensures that your ports will remain open even after your device reboots.

This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

Step 2

Now we are going to login to your ZyXEL P-662H-D1 router. Your router has a web interface, so you will login to it using your web browser. This can be either Chrome, Firefox, Internet Explorer, or Edge. It usually does not matter which browser you choose to use.

Open up your web browser and find the address bar. It should look something like this:

Make sure that the Active checkbox is checked.

Enter the name of the program into the Service Name box. It doesn't really matter what you put into this box, but something that will remind you why these ports are being forwarded is be a good idea.

If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Start Port box and the highest number of that range into the End Port box. If you are only forwarding a single port number then enter that number into both the Start Port and the End Port boxes.

Enter the IP address that you want to forward these ports to into the Server IP Address box. Note that if you are forwarding ports so you can run a program on a device other than your computer then you can enter your device's IP address into that box instead.

When you are done click the Apply button.

Your ports should now be open. It is time to test them.

Now that you have forwarded ports on the ZyXEL P-662H-D1 you should test to see if your ports are forwarded correctly.

To test if your port has been properly forwarded, you can use our Network Utilities tool, which includes a free Open Port Checker. Our Open Port Check tool is the only online port checking tool with Guaranteed Results.
